This is strange, I am failing to reproduce. Both 4.4.1.0 and 4.4.3.0 are working correctly, given the corresponding redirects. I am testing using a Client-Server Application template with WebSharper/WebSharper.FSharp 4.2.9.256 and WebSharper.UI 4.2.5.115. What exact versions are you using?
Just a note that I have managed to get the WebSharper 4.2 working. Things that helped - I've installed F# 4.1 into GAC (previously only had 4.0 - I'm still using VS 2015). That reduced the error message to:
Referenced assembly '...\packages\WebSharper.UI\lib\net461\WebSharper.UI.Templating.dll' has assembly level attribute 'Microsoft.FSharp.Core.CompilerServices.TypeProviderAssemblyAttribute' but no public type provider classes were found.
Then I figured out that this is actually a warning that is turned into error (I have project setting with Warnings level 5 and treat warnings as error). I figured out that this is compiler warning number FS3005 that I simply excluded from warnings in a project setting (--nowarn:3005).
Hi Loïc,
I've used the same package versions that you mentioned. This project that is causing me trouble was upgraded from WebSharper 3.6.x.
I will try to reproduce it from template later as I couldn't get latest WebSharper templates to work with VS 2015 (they seem to stop supporting it).
Also I'm using paket instead of nuget and I will investigate later if that's a possible culprit.

Built with WebSharper |
This issue happens only with WebSharper 4.2, previous 4.1 version works fine.
At compile time I'm getting an exception:
'...\packages\WebSharper.UI\lib\net461\WebSharper.UI.Templating.dll' reported an error: Assembly attribute 'TypeProviderAssemblyAttribute' refers to a designer assembly 'WebSharper.UI.Templating' which cannot be loaded or doesn't exist. Could not load file or assembly 'FSharp.Core, Version=4.4.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
It is an application and I'm referencing a local version of FSharp.Core. I've tried referencing FSharp.Core Assembly Version 4.4.1.0 (Nuget 4.2.3) and Assembly Version 4.4.3.0 (Nuget 4.3.4). Binding redirects were present in both cases.
Where does WebSharper is trying to load FSharp.Core from ?
